Fold change in soluble protein volumetric yield. Fold change represents the log2 of the ratio of the volumetric yield of each protein (in mg per liter of soluble protein) expressed in the CP strain and the volumetric yield of the same protein expressed in the BL strain. Protein expressed at a constant level (ratio of 1) has a log2(ratio) equal to zero, which can be seen as "no change".
